the difference between a 20 and 30 year old is wayyyyyyyyyyyyyy closer than the gap between a 13 and 18 year old. that's a precious couple of years where you learn alot about yourself. both personally and sexually. seriously i would look down less if someone in their 40's were to marry someone in their 20's. i mean i know that can be it's own set of problems but still. i don't care how mature you think you are at 13, you still have alot of growing up to do to catch up to a 18 year old. i mean does anyone realize this girl could possibly be in 6TH GRADE and he is a senior in hs!!! i mean don't they still have crossing guards and recess at that age??? man that just blows my mind!
